Application filed June 4, 1914. Serial No. 842,859.

To all whom it may concern:

Be it known that I, DAVID PETRI-PALMEDO, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented a oer tain new and useful Improvement inSpace- Bandlleleasing Mechanism for Type-Bar Machines, of which thefollowing is a full, clear, and exact description. 1

This invention pertains to type bar 'ma-' chines of familiarconstruction,-that is machines in which a type bar is cast from a lineof justified matrices which are assembled in said machine and are spacedand justified by means of double wedge space bars of generically wellknown construction.

The invention relates particularly to the means whereby said space barsare released one by one, and are allowed to fall onto the assemblingrail behind the last matrix assembled thereon. r

The object of the invention is to provide this so-called space barescapement mechanism in a form which shall be durable and certain in itsaction; and the invention consists in the construction and combinationof parts which are shown in the drawing and hereinafter described andout in the appended claims.

In the drawings, Figure 1 is a front view.

of said invention when the mechanism in front of'the space bands hasbeen removed, and the space band releasing slide and the cover thereforare sectioned. This view shows the parts in their normal position. Fig.2 is a similar view, except that the space band releasing slide and theend space band have both been raised to positions such that said spaceband is about to drop, Fig. 3 is a view of the spacer magazine from theright end thereof and a space band therein when the releasing slide andcover plate have been removed. Fig. 4 is a magnified plan view of theright end of the space band magazine and the space band escapementmechanism and a space band, the parts beingshown in the same relativepositions which they occupy in Fig. 2; Fig. 5 is like Fig. 1, exceptthat thevparts aregreatly magnified, Fig. 6 is a top plan view of thespace band releasing slide. and Fig. 8 is a view from the left sidethereof, as shown in Figs. 1, 2 and 5. a 7

Before beginning a description ofthe S01 called space band escapementmechanism, it

, tain features of the results definitely pointed Fig. 7 is a front viewthereof;

is thought desirable to call attention to cerconstruction of the spacebands themselves, not because these features are novel, butin order thatone may better understand how the present invention is caused to operatein the manner and with hereinafter stated. Each space band comprises ashort wedge 2, and a long wedge 3, which are permanently connected insuch wise that the long wedge may be moved upward relative to the shortwedge for the purpose of effecting the justification of matrix lines.The short wedge has ad jacent its lower end two oppositely extended ears2*; and the long wedge has in its lower edge the vertical notch 3 Thespace bands hang from these ears 2* when the space bands are in theso-called space band magazine, and whenin various other parts of themachine. a

The space band magazine so-called consists of two parallel inclinedrails 13, which are, for most part, the lower walls of clownwardlyinclined grooves 12, which are formed in the opposed faces of twoparallel rail plates 10 which are fixed to suitableframe members 14.These rails 13 at their lower ends are made to extend to the rightslightly beyond the vertical edges of theright ends of the rail plates10 and of the frame members 1 1 by which they are supported. But theseextensions 13 of the rails 13 are quite narrow and project beneathonlyvpa'rts of the ears,- that is to say, the parts of the ears whichare close to the body of the space bar. In other words, the outer endsof these ears project beyond these extension rails 13, asolearly seen inFigs. 4: and 5.;

There are two space band lifters 16. Each of these has at its upper enda horizontal portion 16?, which normally lies beneath the outer end ofthe associated ear on the lowest or foremost space band, and a beveledportion '16 which normally lies below the outer end of the adjacent earof the second space band. These two lifters are simultaneously movableup and down. To make sure that these two lifters shall move up and downtogether, and in order to secure some other advantages which will beapparent, these lifters are formed as integral parts of a slide 17,which slide is mounted in a guideformed between the tight ends of theframe members, 14, and a vertically grooved cover plate 25 fixedthereto. This slide has along its front and rear edges, and extending tothe left therefrom, the vertical flanges 17. The lifters 16 are formedas vertical ribs projecting forwardly and backwardly respectively fromthese two flanges 1:7. This is perhaps an awkward way of describing theslide and its integral parts, as shown; but this manner of describing ithas the advantage of calling'particular attention to the fact that theinvention, broadly considered, does not require that these space bandlifters be parts of a slide.

Having regard merely for the slide itself, irrespective of its primaryfunction of imparting simultaneous up and down movement to the lifters,said slide consists of a metal plate which has a vertical undercutgroove 17 formed in its left face, extending from its lower end upwardto a point which normally slightly below the lowest parts of theextension rails 13. At its upper end 17 this slide is quite thin, andthe left face of this thin part is av material distance to the right ofthe left face of the slide. regarded as a whole. The space band lifters16 are the overhanging vertical flan es of the vertical groove in saidslide. lVith a slide so formed, these lifters not only serve the purposeof lifting the space bands one by one, but also serve as the left wallof the groove or channel 17 down which the space bands fall, and bywhich they are guided so as to fall upon the desired part of theassembling rails 7 between the last matrix M thereon and the line packer8 adjacent thereto.

Rigid with each of the rail plates 10 are the thin plates 30, whoseright ends project beyond said rail plates and overhang the ears 2 ofthe foremost space band. The lower edges 30 of these plates are beveledas shown.

WVhen a stock of space bands are in the magazine, they will be supportedby their ears on the rails 13, and will lie in contact with one another.The forked lower ends of all of said space bands will straddle a fixedrail 35. and will be to the left of an upwardly projecting toe 34 fixedto said rail. This toe is in such a position that the foremost spaceband must occupy the inclined position shown in Figs. 1, 2 and 5, atwhich time the upper end of said space band will engage the adjacentface of the thin upper part1? of the slide 17. The engagement of theforemost space band with this slide, and with this toe prevents it. andall of the other space bands, from sliding off of the supporting rails13. Now, as the slide 17 is 'moved up, carrying the lifters 16 with it.

the horizontal ends 16 of said lifters will engage with the ears on theforemost space band, and will lift it, thereby carrying its lower endabove the toe 34. As said lifters go up, the inclined surfaces 16thereon will engage the ears of the second space band, and will push itand all of the other space bands to the left in said magazine; and thiswill result in moving the upper end of the second space band out ofcontact with the upper end of the foremost space band. Therefore, whenthe foremost space band has been lifted to free its lower end from therestraining influence of the toe 34 this space band will be freed fromall restraint tending to hold it in the inclined position, and thereforeits lower end will swing to the right into the vertical position shownin Fig. 2. As the lifters continue to move up, theears of this spaceband will be carried into contact with the inclined surfaces 30 on theplates 30, and thereby said space band will be pushed to the right untilits ears are pushed off of the horizontal upper ends of the lifters.Thereupon this space band being freed from all restraint will fallvertically downward through the groove 17 in slide 17. and onto theassembling rail 7 between the last matrix M thereon and the usual linepacker 8. When the slide 17 is now moved down to its formerposition,'all of the space bands upon therails 13 will move bv gravityto the right. and the fore most of these space bands will take the sameposition which was formerly occupied by the space band just released.

In the construction shown, the slide 17 is formed with ears 17 whichpass through a vertical slot 25 in the cover plate 25. These ears carrya rod 17 with which the forked end of apivoted lever 36 engages. Byactuating this lever by any suitable means this slide is moved up anddown as required. It is to be understood, however, that this particularmechanism for imparting to the slide and the lifters thereon therequired up and down movement is not at all essential to the presentinvention. Any other means for doing this may be employed.

Having described my invention, I claim 1. In space band releasingmechanism, the combination of a space band magazine having inclinedrails on which the ears of the space bands are suspended, verticallymovable lifters adapted to engage the lower edges of the foremost spaceband, and plates having inclined faces adapted to engage the ears of thespace bands as they are being moved up and to thereby push the spaceband away from the rails and off of said lifters.
